37 is pivoted at one end of its` section39V to the upper endl tlletube 21 at 16 inthe yupper end ofka.,.foap Aff?, which.. lcloses the upper end of the tubef32l-.l ,The bnuehY `mem` ber i341 comprises fa j tubularV bar 48. and

vge'sletlfl anddissecured to! the table" means of screws j 23 extending 4 ,throught ya bristles 49 secured in the outer side thereof. The lower end of the bar 48 is pivoted at 50 to the outer end of the section 40 of The upper end of the bar 34 is pivotally connected to the outer end of the. arm section 4() by means ot hinge joint 51, which includes a pivot 52, a socket bearing in the outer end of said section in which said pivot turns, a wire. 54 connected at its upper end to said pivotand extending down` wardly in the upper end of bar 48, and a spring 55 in said bar connected at its upper end to the lower end ofr said rod, and at its lower end to a pin 56 secured in the bar.

The vsection is cut away below the 'socket bearing 53 at 57 to accommodatethe wire 54 so vthat the Vbrush members 33 and r34may fold together, as shown in dotted lines in Fig. 1. A flat`spring'58 is secured at its-upper end at 59 to the inner side of the bar 48 and bears at its lower end at 60 upon the upper side of the lower arm 35. which spring normally holds the connected "ends of the brush members 32 and 34 swung out slightly, as shown in dotted lines in Fig.

l, so that the brush may be easily unfolded in wiping position when the bottle is placed over the brush in the unit 1.

plurality of rods 61,` preferably four in The bottle holding means 5 comprises a number and rubber sleeves 62 fitted on the upper ends of said rods.

Said rods are secured in the top of the base 3, equi-distant apart, by set screws 63, at a sufficient distanoefrom the center of the base to accommodate the mouth and neck of the bottle 4, and the `rods 61 areV bent outwardly at 64 andthen upwardly at 65, so that the rubber sleeves 62 will engage the side of the bottle and hold the same with the mouth thereof resting upon the gasket- 19.

" In the rbase 3 of each unit are provided L A chain 71 extends over the sprockets 15 of the units 1 and vover a sprocket 72 secured on a power driven shaft 73, rwhich is driven by power through a belt 74 "and a pulley y75 secured on the shaft. Idler sprockets 76 are journaled on shafts 77 'secured in the table 2 and engage the chain 71 from the outfside .between the adjacent sprockets l15 for 0o holding the chain in engagement with the f ylatter sprockets.

The operation of my machineis as follows.

f Before the bottles are placed in the units l the brush 7 is held folded up, as shown in dottedl lines lin Fig. 1. `While thus folded a ,rests upon the gasket 19.y The engagement of the bottom wall of the bottle with the upperbrush member 33, unfolds the brush downwardly until. the bristles 36 of thc brush engage the upper wall of the bottle, the

bristles 49 engage the side wall and the bristles 38 engage the bottom/ wall of the bottle, as shown in full lines in Fig. 1. Water under pressure is introduced through pipe 22, coupling 20, tube 21 and its perfora-V tions 31 into the bottle.

Power being applied through belt 74 and pulley to the shaft 73, the sprocket 72 is rotated, which through chain 7'1vrotates'the sprockets 15 and bases 3 ofthe units 1, to-

gether with the holding means 54 and the" bottles 4 in said units.` The' rotation of ythe bottles causes the brushV 7 to wipe the interior of the bottles 4 and wash the same with water until thoroughly cleaned. The water 'escapes from the bottles through tho mouths thereof and through bore 17, outlets 66. outlets 67 and drains 68 into the tank 70. Then washed the bottles may be lifted out of the units, the brushes 7 folding to permit the same to pass out through the mouths ofl the bottles. v

By loosening the screws 44 the arms 35 and 37 may be extended or shortened. so that the brush will wipe bottles of different diameters, and when so adjusted the brush may be secured in such position by tighteningsaid screws. v

It will be understood that I may change or modify my invention within the scope of the appended claims, without departing from the Vspirit thereof.

What I claim is:
